Versuchsvorschrift

The title compound was prepared according to the procedure described in the preparation of tert-butyl 4-((2-((2S)-bicyclo[2.2.1]heptan-2-ylamino)-5-methyl-4-oxo-4,5-dihydrothiazol-5-yl)methyl)piperidine-1-carboxylate by using 2-(bicyclo[2.2.1]heptan-2-ylamino)-5-(2-(tert-butyldimethylsilyloxy)ethyl)thiazol-4(5H)-one (630 mg, 1.71 mmol), lithium diisopropylamide (Aldrich, 2.0 M in heptane/THF/ethylbenzene, 4.27 mL, 8.55 mmol), and (2-bromoethoxy)(tert-butyl)dimethylsilane (Aldrich, 2.46 g, 10.25 mmol). The title compound was obtained as a sticky orange solid (771 mg). MS (ESI, pos. ion) m/z: 413 (M-TBDMS+2H).
